What's New?

Is it New Bike Time? Always!
07/12/19- Don't waste another nice day on impulse power when you could be riding at Warp 9. Chain Reaction features the very best bikes from Trek & Electra, as well as the highest-quality travel bikes from Bike Friday. Road, Mountain, Hybrid, Electric assist, Kids... we've got them all. Probably the best selection in a single location you'll find anywhere on the peninsula too.
Got a bike that needs repairs?
If you purchased your bike from us, remember that you can bring it in anytime, without calling ahead, for minor on-the-spot adjustments of brakes, gears and wheels (at no charge; this is included with any bike purchased from us). For flat tires, again, no appointment needed. Where possible we try and do flat tires while you wait, but there will be times that's not possible. At most you will be leaving your bike overnight.

For normal (bigger) repairs, our backlog has become so bad that, for the remainder of July, we can no longer take in major work. It is literally a "no room at the inn" situation. This could be the case at many shops known for high-quality service. Not helping matters has been the demise of several local bike shops (the most recent of which is Talbots Cyclery in San Mateo, and several Performance stores), which adds to the strain the remaining shops are feeling.
It's E-Bike time at Chain Reaction! E-Bikes are the latest thing; find out why! Commute to the office without needing a shower, bring home the groceries (even if you live on top of a hill!) or keep up with your obsessive-cyclist partner. Prices start at just $1299 (Oyama folding E-bike) up to the incredible Trek Super Commuter 8 at $5199. They're not a secret anymore; everyone seems to have one. Find out why!
